The Impact of Recurrent Epistaxis on the Quality of Life of Children and the Functioning of Their Families.

Introduction Epistaxis, or nosebleeds, is a common pediatric emergency, impacting their quality of life (QoL). Existing research on epistaxis has predominantly focused on clinical aspects, overlooking its broader impact on the quality of life of affected children and the functioning of their families. This study seeks to fill that gap by assessing the impact of recurrent epistaxis on children's QoL, family dynamics, and parental stress in Saudi Arabia's Eastern region. Methods A survey was conducted involving 168 parents of children with recurrent epistaxis, using the Pediatric Quality of Life InventoryTM (PedsQL 4.0TM) Short Form (SF) for QoL assessment across different age groups, the PedsQL 2.0 Family Impact Module to evaluate the effect of the child's health on family dynamics, and a custom questionnaire for gathering sociodemographic and health-related information. Better QoL and family functioning were indicated by higher scores. Results Recurrent epistaxis was more frequent (>4 times per year) in 58.9% of cases, with unknown causes in 72%. A total of 116 (69%) of the children never needed medical intervention for epistaxis and 52 (31%) visited ER 1-2 times. The lowest scores for both children and parents were in the emotional functioning domains (77.9 and 78.2, respectively). In the study, both parents and children who had no history of ER visits exhibited significantly higher quality of life (QoL) scores compared to those who did, with parents reporting 83.7% versus 77.2% (P=.022), and children showing 84.6% versus 79.9% (P=.049), respectively. Parents of older children, ages 13-18 years, reported a higher Quality of Life (QoL) at 83.9%, compared to those with younger children, ages 2-4 years, who reported a QoL of 57.3% (P=.003). Conclusion The overall QoL scores of families of children with recurrent epistaxis were relatively high, indicating a variable and limited general impact. Significantly higher QoL was observed in families of older children and those without ER visits.

Efficacy and safety of glecaprevir and pibrentasvir in Saudi patients with chronic hepatitis C virus infection at a major tertiary hospital.

OBJECTIVES: To evaluate the effectiveness and safety of glecaprevir/pibrentasvir (GLE/PIB) in chronic hepatitis C (HCV) patients, and to assess the prescribers' adherence to Food and Drug Administration recommendations on treatment duration. METHODS: A retrospective cohort study was carried out on chronic HCV patients of ≥18 years, with or without cirrhosis, naive or experienced, and with normal kidney function or chronic kidney disease (including dialysis patients) at Prince Sultan Military Medical City in Riyadh, Saudi Arabia, between February 2020 and March 2021. The primary effectiveness end-point was the number and percentage of patients who achieved a sustained virologic response (SVR12), virologic failure, and non-response. Safety was determined considering both serious and non-serious adverse events. RESULTS: A total of 92 patients were enrolled in this study. Among patients, 52 (56.5%) were female, 84 (91.3%) were naive, and 45 (48.9 %) had HCV genotype 4. The SVR12 was achieved in 91 (98.9%, 95% CI: [94-99.8]) patients. Only one patient (1.1%, 95% CI: [0.2-5.9]) developed virologic non-response and there were missing data on virologic failure. Overall, non-serious adverse events were observed in 26 (28.5%) patients, and none of them had serious adverse events that led to treatment discontinuation. Approximately 75% of the patients received an inappropriate treatment duration (12 weeks vs. the recommended 8 weeks) and most (n=40, 58%; p<0.022) of the exceedingly long treatments were prescribed by registrars. CONCLUSION: The GLE/PIB was highly effective and safe in chronic HCV Saudi patients.

The impact of acute weight loss following bariatric surgery on Eustachian tube function.

Obesity has emerged as a pressing concern in contemporary society, prompting an increase in bariatric surgery (BS) procedures for severe obesity management. Post-bariatric weight loss might cause complications, such as a reduction in the soft tissue surrounding the Eustachian tube, potentially affecting its function. This cohort prospective study, conducted between May and December 2022, aimed to assess the impact of post-bariatric acute weight loss on Eustachian tube function. A total of 54 cases of bariatric surgery and 157 control subjects were included in the study. Data on socio-demographics, weight, and the type of bariatric surgery were collected for the study group. ET function was assessed using the Eustachian Tube Dysfunction Questionnaire (ETDQ-7). Approximately 55% of the participants fell within the age range of 18-25 years, with the majority (91.4%) having not undergone bariatric surgery. Conversely, participants who underwent BS were significantly more prevalent in the older age groups, specifically those over 50, between 40-50, and 31-40 years (p<0.001). Our sample consisted of 82.5% females and 17.5% males, with BS being significantly more common among male subjects (45.9%) compared to females (21.3%) (p=0.002). The mean total ETDQ-7 in control subjects was significantly higher (11.29±5.49) compared to those who had BS (9.11±4.09). Moreover, when comparing the ETDQ-7 between subjects who had BS and the control group, no statistically significant differences were observed in the total ETDQ-7 score and across all seven items within the ETDQ-7. Based on these findings, bariatric surgery did not have a major effect on ET function.

Assessing the Feasibility of Employing a Combination of a Bacteriophage-Derived Endolysin and Spore Germinants to Treat Relapsing Clostridioides difficile Infection.

Clostridioides difficile is a Gram-positive, anaerobic, spore-forming bacillus and is a major cause of healthcare-associated infections. Whereas the vegetative form of the pathogen is susceptible to treatment with antibiotics, its ability to persist in the gut as antibiotic-resistant spores means that reinfection can occur in cases were the individual fails to re-establish a protective microflora. Bacteriophages and their lysins are currently being explored as treatment options due to their specificity, which minimizes the disruption to the other members of the gut microflora that are protective. The feasibility of employing recombinant endolysins to target the vegetative form of C. difficile has been demonstrated in animal models. In this study, we cloned and expressed the enzyme active domain of LysCD6356 and confirmed its ability to lyse the vegetative forms of a diverse range of clinical isolates of C. difficile, which included members of the hypervirulent 027 ribotype. Lytic activity was adversely affected by calcium, which is naturally found in the gut and is released from the spore upon germination. Our results suggests that a strategy in which the triggering of spore germination is separated in time from the application of the lysin could be developed as a strategy to reduce the risk of relapsing C. difficile infections.

Olfactory Dysfunction following COVID-19 and the Potential Benefits of Olfactory Training.

COVID-19 is associated with a common symptom of olfactory dysfunction, which may persist even after the infection is resolved. Olfactory training (OT) has emerged as the most effective intervention for post-viral olfactory dysfunction. OT involves daily exposure of the olfactory system to various odors. The current study aims to explore olfactory dysfunction following COVID-19 and the potential benefits of olfactory training. METHODS: This is a cross-sectional study conducted among adults aged 18-60 living in Alahssa, Saudi Arabia. An online questionnaire containing an informed consent form and a survey to collect demographic data, vaccination status, level of loss of smell and taste, and the level of awareness about olfactory training (OT) was distributed among all participants who agreed to participate in this study. RESULTS: The study included 524 participants and presented their baseline characteristics, including age, gender, COVID-19 infection status, and complaints. Most patients were female (66.0%), and 46.2% had previously been infected with COVID-19. About 54.8% of participants reported chemosensory dysfunction, while 286 had olfactory dysfunction. Of those, 29.8% had anosmia, 16.8% had hyposmia, and 8.0% had parosmia. Results suggest that being fully or partially vaccinated may offer some protection against olfactory dysfunction compared to being unvaccinated. Adherence to olfactory training was associated with improvement in the sense of smell. CONCLUSIONS: The study highlights the importance of awareness and adherence to olfactory training, which may improve the sense of smell in individuals with chemosensory dysfunction. The findings of this study can inform public health policies and interventions aimed at reducing the burden of olfactory dysfunction associated with COVID-19 vaccination.

Comparison of clinical features and surgical outcomes between hypopnea- and apnea-predominant obstructive sleep apnea.

OBJECTIVES: This study is aimed to investigate the differences in the clinical features and surgical outcomes between hypopnea- and apnea-predominant obstructive sleep apnea (OSA). DESIGN: Cohort study. SETTING: Single tertiary care centre. PARTICIPANTS: This study included 190 patients with OSA who underwent multilevel upper airway surgery between September 2012 and September 2021. The patients were divided into two groups according to the proportion of each respiratory event: hypopnea-predominant (n = 102) and apnea-predominant (n = 88). MAIN OUTCOME MEASURES: The primary outcome measure was the percentage improvement in the apnea-hypopnea index (AHI) from baseline AHI after surgery. RESULTS: The apnea-predominant group included more male patients and had higher AHI, respiratory disturbance index (RDI) and oxygen desaturation index (ODI) than the hypopnea-predominant group. Both groups showed significant improvements in AHI, apnea index, RDI, supine AHI, REM AHI, non-REM AHI, ODI, lowest O2 saturation and Epworth Sleepiness Scale scores following the surgery. Notably, hypopnea index increased after surgery in the apnea-predominant OSA group. Although the improvement in the absolute value of AHI by surgery was significantly greater in the apnea-predominant group than in the hypopnea-predominant group, the two groups showed no significant difference in the percentage improvement in AHI from baseline AHI. CONCLUSION: Patients with apnea-predominant OSA had more severe disease than those with hypopnea-predominant OSA; however, surgical outcomes, as evaluated by percentage AHI improvement, were comparable between the two groups. In addition, multilevel upper airway surgery may induce the transition from apnea to hypopnea in patients with apnea-predominant OSA.

Mechanistic Insights into the Ameliorative Effect of Cichoriin on Diabetic Rats-Assisted with an In Silico Approach.

Type 2 diabetes mellitus is considered to be a substantial socioeconomic burden worldwide on both patients and governments. Coumarins are biomolecules with a diversity of biological activities. The current investigation aimed to explore the ameliorative effects of cichoriin, which is a type of coumarin, on high-fat diet/streptozotocin (HFD/STZ)-induced diabetic rats. METHODS: Rats were allocated into five groups. Group I was considered as the control group, while the other groups were HFD/STZ-induced diabetic rats. Group II was assigned as the diabetic control. Groups III and IV were treated with cichoriin (50 or 100 mg/kg, respectively). Group V received glibenclamide (5 mg/kg) (as a positive control). The blood glucose (BG), serum insulin, triglycerides (TG), total cholesterol (TC), total antioxidant capacity (TAC), catalase, hepatic superoxide dismutase (SOD) and content of malondialdehyde (MDA) were assessed. Histopathological and immunohistochemistry analysis of pancreatic tissue were performed. mRNA and protein expressions of GLUT4, AMPK, and PI3K were estimated. RESULTS: Cichoriin treatment ameliorated HFD/STZ-induced diabetic conditions and mitigated the histopathological characteristics of the pancreas, as well as increasing pancreatic insulin expression. This decreased the levels of BG, TG, TC, and MDA and improved the TAC, catalase and SOD contents. Cichoriin demonstrated upregulation of mRNA and protein expressions of GLUT4, AMPK, and PI3K. The in silico binding of cichoriin with GLUT4, AMPK, and PI3K supported the possible current activities. CONCLUSION: Collectively, this work highlighted the potential role of cichoriin in mitigating HFD/STZ-induced diabetic conditions and showed it to be a valuable product.

Cichoriin, a Biocoumarin, Mitigates Oxidative Stress and Associated Adverse Dysfunctions on High-Fat Diet-Induced Obesity in Rats.

Metabolic dysfunctions linked to obesity carry the risk of co-morbidities such as diabetes, hepatorenal, and cardiovascular diseases. Coumarins are believed to display several biological effects on diverse adverse health conditions. This study was conducted to uncover the impact of cichoriin on high-fat diet (HFD)-induced obese rats. Methods: Obesity was induced in twenty rats by exposure to an HFD for six weeks. The rats were randomly divided into five groups; group I comprised five healthy rats and was considered the control one. On the other hand, the HFD-induced rats were divided into the following (five per each group): group II (the HFD group), groups III (cichoriin 50 mg/kg) and IV (cichoriin 100 mg/kg) as the treatment groups, and group V received atorvastatin (10 mg/kg) (as a standard). Triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), alanine transaminase (ALT), aspartate transaminase (AST), creatine kinase MB (CK-MB), urea, creatinine, the hepatic and renal malondialdehyde (MDA) as well as reduced glutathione (GSH) levels were assessed. Histopathological analysis of the heart, kidney, and liver tissues was investigated. mRNA and protein expressions of the peroxisome proliferator-activated receptor gamma (PPAR-γ) were estimated. Results: The administration of cichoriin alleviated HFD-induced metabolic dysfunctions and improved the histopathological characteristics of the heart, kidney, and liver. Additionally, the treatment improved the lipid profile and hepatic and renal functions, as well as the oxidative balance state. Cichoriin demonstrated an upregulation of the mRNA and protein expressions of PPAR-γ. Taken together, these findings are the first report on the beneficial role of cichoriin in alleviating adverse metabolic effects in HFD-induced obesity and adapting it into an innovative obesity management strategy.

Brassica oleracea L. var. botrytis Leaf Extract Alleviates Gentamicin-Induced Hepatorenal Injury in Rats-Possible Modulation of IL-1ß and NF-κB Activity Assisted with Computational Approach.

BACKGROUND: Recently, crop byproducts are considered a hot topic and can be converted into beneficial products. Cauliflower is well-known for its protective effects against oxidative stress-induced damage. The current study aimed to investigate the chemical profile and the ameliorative effects of cauliflower leaf extract (CL) on gentamicin-induced renal and hepatic injuries in rats. METHODS: Cauliflower leaf was extracted with methanol to give the total methanol extract (TME) followed by the determination of total phenolic contents (TPC). Rats were divided into five groups; Group I was assigned as the control group, while the other groups were injected with gentamicin for ten days. Group II was given distilled water. Rats in groups III and IV were treated with oral CL (200 mg/kg and 400 mg/kg, respectively). Group V received L-cysteine (as a positive control). The functions of the kidneys and liver; oxidative stress and morphological and apoptotic changes of renal and hepatic tissues were assessed. RESULTS: The TME was subjected to chromatographic techniques to yield ferulic acid, vanillic acid, p-coumaric acid and quercetin. TPC was 72.31 mg GAE/g of dried extract. CL treatment dose-dependently ameliorated gentamicin-induced impaired kidney and liver functions and improved the histopathological appearance of both organs. It also reduced gentamicin-induced oxidative stress. CL demonstrated downregulation of mRNA and protein expressions of IL-1ß and NF-κB compared to nontreated rats. In silico interaction of the isolated compounds with amino acid residues of IL-1ß and NF-κB might explain the current findings. CONCLUSION: Taken together, this study raises the waste-to-wealth potential of cauliflower to mitigate gentamicin-induced hepatorenal injury and convert the waste agromaterials into valuable products.

Voice Disorders Among Teachers in Al-Ahsa, Eastern Region, KSA: Vocal Complaints, Treatment-Seeking Behaviors, and Knowledge of Vocal Care.

BACKGROUND: Voice disorders are a serious and common complaint among teachers, yet there are no published studies on these conditions in the context of Al-Ahsa city in the eastern region of the Kingdom of Saudi Arabia. This study analyzed the vocal complaints of Saudi teachers, investigated their treatment-seeking behaviors, and assessed their knowledge of vocal care. METHODS: A cross-sectional online survey was randomly distributed to 604 Saudi teachers from December 2021 to March 2022. The data included sociodemographic characteristics, academic statuses, vocal symptoms and their effects, and attitudes toward voice problems. Statistical analysis was done using the Statistical Package for the Social Sciences (v. 23). Categorical variables were expressed as frequencies and percentages. A chi-square test was conducted to verify the association between the categorical variables. RESULTS: Of the participants, 62.1% were female. 65.4% reported having voice-related problems, with the most frequently reported symptoms being hoarseness (68.35%), throat dryness (60.76%), and sore throat (56.46%). Out of the participants who reported voice problems, 32.15% stated being affected by absenteeism from school. Only a minority of teachers sought medical help (5.1%) or received information about the vocal care (29.5%). The factors that were found to be significantly associated with voice complaints include female gender, positive family history of vocal disorders, speaking in a loud voice, being non-smoker, and having the high number of classes per week (P < 0.05). CONCLUSION: Voice-related complaints were highly prevalent among Saudi teachers for multiple factors, most of which were manageable. This study strongly recommends the vocal educational programs to be implemented during student teacher training.

Indications and complications for surgical management of thyroid diseases: A single center experience.

Background: Thyroid disorders are one of the most common endocrine disorders. Thyroid disorders are highly prevalent in the Saudi population. There are many approaches to treat thyroid disorders, varying from conservative to surgical, depending on the severity of each condition. There are many indications for surgical management of thyroid diseases, including carcinoma, hyperthyroidism, and local compression symptoms. Materials and methods: This is a retrospective study included subjects operated upon for a thyroid disorder over 6 years period in the eastern province of Saudi Arabia. Results: The clinical manifestations and postoperative characteristics of the patients are given in Table 2. It can be observed that the most dominant clinical presentation was neck mass (76.4%), while the most common indication of surgery was the suspicion of cancer (54.5%). Furthermore, the most common histopathology was papillary thyroid cancer (41.8%), whereas the most common complication after the surgery was hypocalcemia (9.1%). Likewise, total thyroidectomy was the most commonly sought surgical intervention (70.9%). Additionally, Bethesda class III constitutes 35.1%, while Bethesda class II constitutes 29.7%. Conclusion: Suspicion of cancer was the most prominent indication for surgical intervention. The most prevalent postoperative complications were hypocalcemia. Furthermore, papillary thyroid carcinoma was the most common histological findings, which raises several questions since it contrasts with previous studies done in Saudi Arabia. We believe that the number of thyroid procedures in our region is underreported, and more research is needed to validate this.

The Effect of Online Teaching on Vocal Health Among Saudi Teachers During COVID-19 Pandemic.

PURPOSE: The goal of this study is to determine how online education affects the vocal health of schoolteachers in Saudi Arabia's Eastern Province. Teachers' phono trauma is well-known as a serious occupational hazard, and online education was the primary mode of delivering instruction to students during COVID-19. METHODS: This is a descriptive cross-sectional study conducted among teachers in the Eastern Province area of Saudi Arabia. Teachers completed a self-administered questionnaire via an online platform, which included socio-demographic data, academic status, and the Voice Handicap Index-10 questionnaire, which assessed their vocal difficulties. RESULTS: A total of 335 teachers responded to the survey (78.2% females vs. 21.8% males). Nearly half (48.7%) were primary school teachers. 45.7% were currently teaching distance learning. Earphones and microphones (49.3%) were the most commonly used distance learning accessories. Noise in the classroom was a very much disturbing factor in teaching implied by 44.8% of the teachers. During the COVID-19 pandemic, the vocal handicap index-10 was significantly higher among females (P = 0.007), primary school teachers (P < 0.001), moreover those currently teaching distance learning (P = 0.001) and those who perceived that there is more work in distance teaching (P < 0.001). CONCLUSION: Compared to in-person teaching, online teaching may have a positive impact on vocal health among Saudi teachers. Of all the teachers, phono trauma tends to be more among females who were primary school teachers, currently teaching distance learning, and those who perceived distance learning to be laborious.

Awareness about first aid management of epistaxis among medical students in Kingdom of Saudi Arabia.

BACKGROUND: Epistaxis is the bleeding from nose or nasal cavity and it is considered as one of the most common emergencies presenting in ear, nose, and throat department and accident and emergency department worldwide. OBJECTIVE AND AIM: The aim of this study was to assess and evaluate knowledge, attitude, and practice of first aid management of epistaxis among medical students in the Kingdom of Saudi Arabia. MATERIALS AND METHODS: A cross-sectional community-based studies were collected using electronic questionnaire distributed among medical students all over the Kingdom of Saudi Arabia. The study was conducted between September and January 2018. RESULTS: Data were collected from 300 medical students from all over the Kingdom of Saudi Arabia using questionnaires, which were filled electronically. Majority of the respondents were females (75.7%), whereas 24.3% of the respondents were males. Most of the participants were from fourth and fifth year with 25.0 and 24.3%, respectively. 39.7% of the participants responded that fingernail trauma as the commonest cause of the epistaxis, followed by bleeding disorder in 17.3%. 64% of the respondents think that epistaxis is an emergency condition that requires early intervention. 71% of the respondents demonstrated the correct position as first aid measure of epistaxis and only 41.3% of respondents demonstrated the correct site for pinching the nose. The main source of the respondent's knowledge regarding first aid management of epistaxis was self-taught (53.67%) followed by medical books (23.33%). CONCLUSION: Medical students in Saudi Arabia have an adequate knowledge about epistaxis and first aid measure that can be used to manage epistaxis.

Long term antidepressants prescribing in the Psychiatry Department at Riyadh Military Hospital. Cross-sectional study.

OBJECTIVE: To ascertain the long-time presenting patients on antidepressant at Riyadh Military Hospital. METHODS: A cross-sectional study was carried out in the Psychiatric Department, Riyadh Military Hospital, Riyadh, Saudi Arabia from July 2009 to September 2010. Patients' files were randomly searched for patients who were on antidepressant >/=18 months, were aged >/=18 years, and undergoing psychiatric consultation. Then the patient pharmacotherapy regimens were extracted, including the antidepressants and duration of antidepressant prescribing. RESULTS: Of the 120 patients files we searched, the duration of antidepressant prescribing ranged from one to more than 6 years; 20% were prescribed for 2-3 years, 19.2% for 3-4 years, 18.3% for 1-2 years, 16.7% for more than 5 years, and 12.5% for 4-5 years. CONCLUSION: In this study, more than 60% of the patients were taking the antidepressant for more than 2 years. While antidepressants are the gold standard therapy for depression, long term prescribing needs to be reasonable. Antidepressant medication generally should be taken for 6-9 months after a first episode of depression.
